How the formula works
Both attojoule and exajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attojoules by 1.000000000e-36 to get exajoules. To reverse the conversion, multiply a exajoule value by 1.000000000e+36 to get back to attojoules.
Frequently asked questions
What is Attojoule (aJ)?
A attojoule (aJ) is a metric-prefixed unit of energy equal to 10-18 joules, a fraction of a single joule, using the SI atto prefix.
What is Exajoule (EJ)?
A exajoule (EJ) is a metric-prefixed unit of energy equal to 1018 joules, using the SI exa prefix.
How do I convert attojoules to exajoules?
Multiply the attojoule value by 1.000000000e-36 to get the equivalent in exajoules. For example, 5 aJ × 1.000000000e-36 = 5.000000e-36 EJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-36 is an exact, non-rounded value.
Can I convert exajoules back to attojoules?
Yes. Divide the exajoule value by 1.000000000e-36, or multiply it by 1.000000000e+36, to get attojoules.
